摘要：为解决廊固凹陷万庄地区沙三段地层勘探开发程度低以及油藏单元各要素认识不成熟的问题, 从而推进油气藏评价与建产工作, 笔者采用了一种综合测井解释结论资料? 试油和生产动态等资料相结合的方法, 对沙三段地层的油藏单元进行了详细的研究? 通过梳理砂体展布与构造特征, 对各油藏单体的连通关系进行了分析, 重新厘定了单元边界, 并明确了油气藏有利发育单元? 研究结果表明: 研究区纵向上可以分成 12 套单元层系, 其中 Es3 2 底各层系油藏单元主要发育于 T12? Q56? T47 和 Q87 区块? Es3 3 上各层系油藏单元较多, Es3 3 下各层系油藏单元数量有所减少, 主要集中于 T12 区块? 总体上看, 各区块主要油藏单元仍然以构造控制为主, 断层发挥着重要遮挡作用? 此外, 河道化砂体上倾尖灭与断层配合也可形成众多构造??岩性圈闭, 是油气藏发育有利位置?

Abstract: To address the low level of exploration and development and the immature understanding of reser? voir unit elements of the third member of Shahejie Formation (Es3 ) in Wanzhuang area of Langgu Sag, so as to pro? mote the evaluation of hydrocarbon reservoirs and production establishment, a comprehensive method of combining logging interpretation conclusion data, oil test and production dynamics data was adopted for studying the reservoir units in detail. By organizing the distribution and structural characteristics of sandy bodies and analyzing the con? nectivity among individual reservoir unit, the boundaries of the reservoir units were redefined and the favorable de? velopmental units of hydrocarbon reservoirs were clarified. The research results indicate that the study area can be vertically divided into 12 sets of unit systems. Among them, the reservoir units of the lower series of Es3 2 are mainly developed in blocks T12, Q56, T47, and Q87. Reservoir units mainly concentrate in block T12. There are more reservoir units in upper Es3 3 , while there are less in lower Es3 3 . Generally, the reservoir units of each block are still primarily controlled by structures, with faults playing a significant role in shielding. In addition, the coopera?tion of channel sand bodies and faults can also form many structural?lithologic traps, which are favorable locations for the formation of reservoirs.

Keywords: Es3 reservoir unit Langgu Sag sand body distribution Wanzhuang area
